Description

Technical Field

[0001] This utility model relates to the field of baijiu lees turnover bucket technology, specifically a lees turnover bucket based on baijiu brewing. Background Technology

[0002] The mobile turnover hopper for baijiu brewing is a specialized device used in traditional solid-state baijiu brewing for the efficient, hygienic, and convenient transfer and temporary storage of mash. In traditional baijiu brewing, the mash needs to be frequently transferred between processes such as leaving the fermentation pit, mixing ingredients, and returning to the fermentation pit. Manually using shovels, baskets, etc., is extremely labor-intensive and inefficient. Therefore, a mobile turnover hopper for baijiu brewing was designed.

[0003] A driving device is needed in the production process of a rotating hopper for baijiu (Chinese liquor) brewing. Chinese utility model patent CN217916487U discloses a rotating hopper for material feeding, comprising a hopper, a discharge hopper, a discharge pipe, and a discharging device. The hopper, discharge hopper, and discharge pipe are connected sequentially from top to bottom. The discharging device includes a bearing seat, a rotating shaft, and an insert plate. The bearing seat is vertically mounted on the outer wall of the discharge pipe. The rotating shaft is vertically mounted at the bottom of the bearing seat. The rear end of the insert plate is connected to the rotating shaft and can rotate horizontally based on the rotating shaft; a handle is provided at the front end. A groove is provided on the side wall of the discharge pipe, into which the insert plate can be inserted. This utility model can solve the problem of efficient material transfer in injection molding workshops, and can be used for material feeding with controllable discharging speed. It has a simple structure, is safe and reliable, and is highly practical. This utility model utilizes a feeding device that combines a rotating shaft, an insert plate, and a slot structure to achieve feeding, stopping feeding, and control of the feeding speed. Feeding begins when the insert plate rotates open and stops when it is fully inserted into the slot. The feeding speed can be adjusted by controlling the opening of the insert plate, making it practical and efficient. The insert plate is thin, facilitating insertion and removal. Its circular structure perfectly matches the structure of the discharge pipe, preventing leakage. The slot opens horizontally inward from the outer wall of the discharge pipe to the axis, forming a semi-circle when viewed from above. Combined with a handle, the opening of the insert plate can be finely adjusted, making the feeding speed controllable.

[0004] However, the utility model can be used for material handling hoppers. The design of the hoppers in injection molding workshops has serious deficiencies and shortcomings in key aspects such as automation, precise flow control, hygiene, equipment mobility, and long-term operational stability. In addition, it lacks a cleaning structure, and manual cleaning is required when the hopper needs to be cleaned, which is slow and complicated. Therefore, a hopper based on the fermentation process of liquor production is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a movable turnover bucket for lees in baijiu brewing. Through motor-driven threaded transmission, it drives an automated unloading mechanism with lever linkage, significantly improving the efficiency and operational safety of lees transfer. The dual-guide system of slide bar and arc-shaped trough ensures operational stability. The modular cleaning and mobile design takes into account both hygiene management and production line flexibility, thus solving the core pain points of traditional brewing, such as high manual transfer intensity, difficulty in hygiene control, and insufficient equipment flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 In this embodiment, a lees turnover hopper based on baijiu brewing includes a base plate 1, a support frame 3 fixedly connected to the top of the base plate 1, a drive device 2 inside the support frame 3, and a hopper 5 on the top of the base plate 1.

[0025] The driving device includes a motor 201 fixedly connected to the top of the support frame 3. The output shaft of the motor 201 is rotatably connected to a threaded rod 202. The bottom of the threaded rod 202 is rotatably connected to the top of the base plate 1. Two limiting blocks 203 are fixedly connected to the surface of the threaded rod 202. Threaded blocks 204 are threadedly connected to the surface of the threaded rod 202. Two sliding rods 206 are fixedly connected to the bottom of the support frame 3. The bottom of the sliding rods 206 is fixedly connected to the top of the base plate 1. The surfaces of the two sliding rods 206 penetrate the interior of the threaded blocks 204. A first connecting block 205 is fixedly connected to the surface of the threaded blocks 204. A first connecting rod 207 is rotatably connected to the inner side of the first connecting block 205. A second connecting block 6 is fixedly connected to the right side of the hopper 5. The inner side of the second connecting block 6 is rotatably connected to the interior of the first connecting rod 207.

[0026] Specifically, motor 201 drives threaded rod 202 to rotate, and threaded rod 202 converts the rotational motion of motor 201 into the linear motion of threaded block 204. Both ends are rotatably connected to the motor output shaft and the base plate 1 respectively to ensure stable rotation. Limiting block 203 restricts the movement range of threaded block 204 to prevent it from disengaging from threaded rod 202 or running over its travel. Threaded block 204 moves linearly along threaded rod 202, converting rotational motion into linear displacement. Sliding rod 206 passes through threaded block 204 to constrain its movement trajectory and avoid swaying. First connecting block 205 is fixed on the surface of threaded block 204 and connects to first connecting rod 207 to transmit the linear motion of threaded block to hopper 5. The two ends of first connecting rod 207 are hinged to first connecting block 205 and second connecting block 6 respectively, converting the vertical motion of threaded block into the tilting motion of hopper 5. Second connecting block 6 is fixed on the side of hopper 5 and serves as the fulcrum of first connecting rod 207 to push hopper 5 to rotate around the hinge point. Hopper 5 achieves tilted unloading under the push of connecting rod.

[0027] Secondly, two support plates 4 are fixedly connected to the bottom of the support frame 3. The two support plates 4 are rotatably connected to the hopper 5 on opposite sides. The bottom of the two support plates 4 is fixedly connected to the top of the base plate 1. The support frame 3 fixes the top of the motor 201 and the slide rod 206 to provide structural rigid support. The base plate 1 fixes the bottom of the slide rod 206 and the bottom end of the threaded rod 202, serving as the mounting base for the entire device. The support plates 4 reinforce the hopper 5 or provide auxiliary support.

[0028] In this embodiment, a second connecting rod 7 is fixedly connected to the bottom of the hopper 5, and a roller 8 is rotatably connected to the inner side of the second connecting rod 7. A fixing block 9 is fixedly connected to the top of the bottom plate 1, and an arc-shaped groove 10 is provided on the top of the fixing block 9. The surface of the roller 8 is in rolling connection with the inner side of the arc-shaped groove 10. The second connecting rod 7, the roller 8, the fixing block 9, and the arc-shaped groove 10 cooperate to guide the hopper 5 to flip along the arc-shaped trajectory, ensuring smooth movement.

[0029] It should be noted that the top of the hopper 5 is connected to the feed pipe 11, and the left outer wall of the hopper 5 is connected to the discharge trough 12. The inner wall of the discharge trough 12 is provided with a guide rail 13, and an insert plate 14 is slidably connected to the inner side of the guide rail 13. The surface of the insert plate 14 penetrates the top of the discharge trough 12 and extends into the interior of the discharge trough 12. The top of the hopper 5 is provided with a main water pipe 15, and a water valve 16 is fixedly connected to the left side of the main water pipe 15. Several water supply pipes are fixedly connected to the bottom of the main water pipe 15, and the surface of the water supply pipes penetrates the top of the hopper 5 and extends into the interior of the hopper 5. Inside, nozzles are fixedly connected to the bottom of the water supply pipes. The bottom plate 1 has a groove inside, and four wheels 17 are fixedly connected to the bottom of the bottom plate 1. The four wheels 17 are arranged in a rectangular shape. The feed pipe 11 conveys materials into the hopper 5. The discharge trough 12 and the insert plate 14 slide along the guide rail 13 to control the opening or closing of the discharge trough 12 and adjust the discharge flow rate. The main water pipe 15 and the water valve 16 inject water into the hopper 5 for cleaning or mixing materials. The water valve 16 controls the water flow. It is installed at the bottom of the bottom plate 1 to realize the overall movement of the equipment.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, motor 201 starts, driving threaded rod 202 to rotate. Threaded block 204 engages with threaded rod 202 through its internal thread. Because slide rod 206 passes through threaded block 204, restricting its rotation, threaded block 204 is forced to rise and fall vertically along the axis of slide rod 206 and threaded rod 202. When threaded block 204 rises and falls, it pushes or pulls second connecting block 6 on the right side of hopper 5 through first connecting block 205 and first connecting rod 207. The left side of hopper 5 is hinged to bottom plate 1 through support plate 4. When the right side of hopper 5 is lifted by first connecting rod 207, hopper 5 tilts counterclockwise around the hinge point of support plate 4. When the right side is pulled down, hopper 5... 5. Reset clockwise to horizontal. The roller 8 at the bottom of the hopper 5 is fixed by the second connecting rod 7. The roller 8 rolls along the arc-shaped groove 10 on the fixed block 9, forcing the hopper 5 to move along a predetermined arc-shaped trajectory. When the hopper 5 is tilted, the mash inside slides down to the discharge trough 12 under the action of gravity. The discharge port can be opened and closed by manually inserting and removing the insert plate 14 in the guide rail 13 to control the discharge volume. After the water valve 16 is opened, clean water is transported from the main water pipe 15 through the water supply pipe to the nozzle and sprayed into the hopper 5 for cleaning. The entire turnover hopper is moved and transported horizontally by the four wheels 17 at the bottom of the base plate 1.
